Overview

Silimanite brick is a kind of refractoriness which made by silimaniteand other minerals. And silimanite can be transformed to be mullite under more 1500℃ high temprature.
Silimanite brick are mainly used in high temprature furnaces, such as glass melting furnace,etc.

►The main applications are:
◆ Rider arches
◆ Forehearth superstracture
◆ Bushing for rochwool and fiber glass

►Specifications:
◆ Dense structure
◆ Good thermal shock resistance

►Advantages:
◆ Corrosion-resistant
◆ High quality
